You and I apparently like to do things the hard way. Lone Gunman has an Evans too, and could give you some advice. Find him on the NCOWS page and PM him.
Go to this website
www.leverguns.com/articles/blancard/evens.htmIt's a very informative article. It says brass can be made from 30-40 brass. I think LG said he uses 300 Savage, others say they use 44 magnum, but regardless, you have to have the rims turned down. Quite expensive if you have to pay to have it done, especially if you want a 100 rounds or so.
There was a guy on eBay selling factory Evans bullet molds. The first one went for $61, and I forgot to bid on it. The next one went for about $160, and a third one for $200! Guess word got around. You could get a bullet from someone with an original mold, and have one made for less than that.
They have variable bore diameters, so slugging your barrel is a must. The guy in the article recommends doing a chamber cast also.
Mine has an odd barrel length, so it might be a rifle that's been cut down.
Also, post on
www.antiqueguns.com in the pre-1898 forum, and ask about cases and bullets. If there's a shooter out there, that's where he'd be.
